Manziel gathered the NFL coaches, general managers, and scouts prior to his workout and then went on to do a 60-play script for about 45 minutes.

Eight NFL coaches were in attendance, five among teams that have a top 10 pick in May’s NFL Draft, which included the Houston Texans and head coach Bill O’Brien. Houston has the first pick in the draft.

Former president George H.W. Bush and wife Barbara were brought in by a golf cart and received a lot of attention on the sidelines.

Manziel wore a helmet and shoulder pads and threw only two balls that hit the ground.

Manziel became the first freshman ever to win the award the Heisman Trophy in 2012 and threw for 3,732 yards and 33 touchdowns while running for 686 yards and eight touchdowns last season.
